Our pump bearings noisy, had small engine shop repair hook back up , now ce reports on heater ????


Pump bearings, hook up, CE error...not following your sequence of events here. CE error on a Hayward heater means a problem with the control board communicating with the display board. Generally it means you need a new display/bezel assembly. None of this should have anything to do with a motor repair unless at some point during all this someone grounded out line power and sent a surge thru the system in the process.

I have a CE error code on my Hayward Pool heater. This happened after a heavy rain. Should I try a hairdryer?


According to a Hayward manual the CE error code is a communication error. Here is quote, "If communication between the ignition board and the display board is not established
within 3 s of power-up an error will be displayed. After communication is
established, if it is lost for 30 s, the error will be displayed. The error code will
be cleared upon a valid data exchange between boards."

I don't think you can do any harm by turning the power off, opening the cover and drying everything out the best you can. In addition, if you carefully unplug and then replug each of the connectors then that may also help correct a communication error.

I hope this helps and please vote on this answer. Thank you.

The code CE is showing on my Hayward pool Heater what does that mean and can I fix it


I have just repaired my H400 series pool heater from the 3rd CE error in only 3 years since the pool and heater were installed. In each case the circuit board (F0059-456600) was in some way to blame .... I will explain.
Case 1 : Only months after installation the CE error came up. Rain water had got in around the display module and water-damaged the circuit board. It was replaced under warranty. Since then I keep a big plastic lid covering the display unit when the heater is not in use.
Case 2 : 1 year from new the CE error came back. On investigation it was found that a rat had managed to get inside the heater (there are big gaps around the pipe entries) - it had then partly chewed through the ribbon cable joining the two circuit boards together. Display circuit board was replaced at my cost - and all was well again. I also rat-proofed the heater - eliminating all the big openings with chicken wire.
Case 3 : Fired up the pool heater for the first time this year and CE came up. I pulled the display module and this time found obvious signs of blackening / burning on the display circuit board under the big green resistor (R1). Luckily I had kept the old circuit board from the previous time and was able to make 1 good board from the two I had - back in action now.
So in my experience it has been the display circuit board each time - and it only takes a phillips-head screwdriver and about 10 minutes to get it out.

Have a Hayward H400 FDP. CE error, probably year or so. If the boards have to be replaced, why together, versus replace the one that is bad?


The CE error code means Communication Error. This is a loss ov communication between boards. It could be the wiring, it could be no power to one of the boards. There is a possibility that if you have a short circuit in one board that is bad, and you replace the other one, that it could damage the new board too. Do you have your manual? you can download one from www.haywardnet.com

Error code "CE" is being displayed. I was told to replace the control board, which I did. Still getting the error message. Does the system need to be restarted to recognize the new board? If so,...


Error code "CE" is "Communication Error" the manual for your heater gives the following description.. "If communication between the ignition board and the display board is not established within 3 s of power-up an error will be displayed. After communication is established, if it is lost for 30 s, the error will be displayed. The error code will be cleared upon a valid data exchange between boards.
That being said If you replaced the board I would check all your connections closely and look for bent pins, corroded/oxidized connectors, etc. If this still does not help give Hayward a call, they usually give pretty good support. You can reach them at 908-351-5400

I have an H400 heater (H400IDL2) and I get the CE trouble code, how can you determine which board is bad?


CE is a communication error between the display board and the ignition board. If you've had a lot of rain lately it could just be that moisture inside the unit is causing the error rather than a bad board. Take the cover off and blast the inside with a hairdryer for a few minutes, making sure to get the boards and connecting wires. That sometimes clears the error.

CE ERROR


CE is a communication error.

This is an automatic check performed anytime the unit is powered up. If there is no data communication between the main panel and the ignitor you will get this code within 30 seconds.

If communication is re-established this code will disappear.

DO NOT do any of the following with AC power on / to the unit.

First check the ignitor then, the wiring and terminals from the ignitor to the main board.

There just might be a corrosion problem with the circuitry or corrosion on the main board itself.

Thanks for using FixYa.

Pool Heater with communication (CE) Error


Code "CE" stands for communication error and describes a fault between the mother board and the display. I doubt it's the relay causing it though...
